  • DEAR COLLEAGUES, A major benefit of the VCR technology is the CO2 improvement for gasoline powertrains. Tailoring of the compression ratio to the engine load, leads to a significant fuel consumption reduction for the customer. Nowadays, enlargement of the λ=1 operating area to fulfill RDE legislation is an additional major benefit. The effectiveness of the VCR technology can be demonstrated on a gasoline engine with a specific power output of 90 kW/l. To achieve this power, enrichment for component protection of approximately λ = 0.8 is required. Applying stoichiometric operation (λ = 1) in the entire map leads to a power drop of 27% (to 66 kW/l) with a constant exhaust temperature of 980 °C. The 2-stage VCR technology enables the full recovery to the initial power level under RDE compliant boundary conditions. Furthermore, significant fuel consumption benefits of 4.1% in WLTC is achieved (Please read the full paper: “All Lambda 1 Gasoline Powertrains” from 5. Internationaler Motorenkongress in BadenBaden).

    Varying the compression ratio on Diesel engines results in reduced peak firing pressures, beneficial for lowered thermo- mechanical stress. Additionally the cylinder temperature decreases which leads to reduced engine-out pollutant emissions. This enables two different opportunities for VCR application: Extending the power output on an already peak firing pressure limited base engine or rightsizing the bearing dimension according the reduced peak firing pressure which enables friction reduction and finally an improved fuel consumption. On top of these mechanical advantages, VCR provides potential to lower engine-out NOx under higher operating loads, important for optimal compliance of future RDE demands. Dual fuel engines suffer from the compromise for the compression ratio. E g. marine engines require a low compression ratio for the gas application while running most of the time on heavy fuel oil where the high compression ratio would enable fuel consumption and operator cost reduction.

    The FEV conference on „Variable Compression Ratio” will tackle various of these aspects, reviewing the state of the art and introduce new VCR solutions. Apart from the deep insight into latest VCR research and developments, this new platform offers multiple opportunities for mutual exchange with reputable industry representatives and engineering experts.
